Most users consider this a good thing.  It makes it easy to get things back
that you delete, although I suppose the advent of unlimited undo's has made
this less important than it was in the old days.

I don't think there's a built-in option for this.  You could advise all the
commands that you don't want to save, with something like

(defconst disable-kill-ring-advice
  (ad-make-advice 'disable-kill-ring nil t
                  '(advice lambda ()
                           (let ((kill-ring nil))
                             ad-do-it))))

(defun disable-kill-ring (function)
  (ad-add-advice function disable-kill-ring-advice 'around 'first))

(mapc 'disable-kill-ring '(kill-word backward-kill-word kill-line ...))
